Wave Velocity

Wave velocity is a wave property, which may refer to:

  • phase velocity, the velocity at which a wave phase propagates at a certain frequency
  • pulse wave velocity, the velocity at which a pulse travels through a medium, usually applied to arteries as a measure of arterial stiffness
  • group velocity, the propagation velocity for the envelope of wave groups and often of wave energy, different from the phase velocity for dispersive waves
  • signal velocity or information velocity, which is the velocity at which a wave carries information
  • front velocity, the velocity at which the first rise of a pulse above zero moves forward

Famous quotes containing the word wave:

    Children are as destined biologically to break away as we are, emotionally, to hold on and protect. But thinking independently comes of acting independently. It begins with a two-year-old doggedly pulling on flannel pajamas during a July heat wave and with parents accepting that the impulse is a good one. When we let go of these small tasks without anger or sorrow but with pleasure and pride we give each act of independence our blessing.
    Cathy Rindner Tempelsman (20th century)
